CENTRAL SCIENTIFIC CO., CHICAGO, U. S. A. 



No. 1044E. 



BATTERIES, Storage, Exide Laboratory. These batteries are extensively used in scientific 



laboratories, both in this country and Europe. We guarantee them to give good service at the 



capacities designated. 

 The voltage of each cell of all capacities is slightly above two volts on open circuit and during 



discharge at the eight-hour rate varies from that point at the beginning to 1.75 volts at the end. 

 We have selected types that are adapted to the various laboratory demands. Other sizes will be 



quoted upon application. Cells must be charged before using. All cells are in glass jars. 

 The prices given include the electrolyte and connecting bolts. 

 Note: If desired for permanent installation in units of two or more, cells may be ordered with 



connecting straps burned together.
